Description

[Technical Field]

[0001] This specification discloses a component mounting line and a method for recovering waste tape. [Background technology]

[0002] Conventionally, there has been known a component mounting line in which component mounters, each of which includes a mounter main body that mounts components supplied from a tape feeder onto a board and a waste tape transport device that transports the waste tape after the components have been supplied, are arranged along the board transport direction. For example, Patent Document 1 discloses that the waste tape transport device provided in each component mounter can deliver waste tape to the waste tape transport device of an adjacent component mounter downstream in the board transport direction. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2015 / 045018 Summary of the Invention [Problem to be solved by the invention]

[0004] Tape feeders that supply components to component mounters may be either paper tape or plastic tape. In this case, waste tape generated on the component mounting line disclosed in Patent Document 1 is transported in a mixed state of paper and plastic waste tape, and is collected in a collection box located next to the component mounter located at the end. When disposing of waste tape, it is desirable to separate it according to its material, but on the component mounting line disclosed in Patent Document 1, it was difficult to separate the waste tape.

[0009] In this second component mounting line, only waste tape made of the first material is transported downstream in the board transport direction, which makes it easier to separate the waste tape compared to when the tape feeder is set in the mounting machine body or the transport direction of the waste tape transport device is determined without considering the material of the waste tape.

[0010] The first waste tape recovery method of the present disclosure includes: A waste tape recovery method used in a component mounting line in which a plurality of component mounters are arranged side by side in a board transport direction, the method comprising: a mounter main body that receives a supply of components from a first tape feeder that supplies components using a tape made of a first material containing a plurality of components, or a second tape feeder that supplies components using a tape made of a second material, and mounts the components on a board; and a waste tape transport device that can transport the waste tape after supplying components both upstream and downstream in the board transport direction, the first tape feeder is set in the mounting machine bodies of a first group of consecutive component mounters, which includes a component mounter located furthest upstream in the board transport direction among the plurality of component mounters and a predetermined component mounter; the second tape feeder is set in a mounter body of at least one of the mounters adjacent to the predetermined mounter downstream in the board conveying direction among a second mounter group other than the first mounter group; setting a waste tape transport direction in a waste tape transport device of the first component mounter group to the upstream side of the board transport direction; The gist of the present invention is that the waste tape transport direction in the waste tape transport device of the second component mounter group is set downstream of the board transport direction.

[0011] In this first waste tape recovery method, only waste tape made of the first material is transported upstream in the board transport direction, which makes it easier to separate the waste tape compared to when the tape feeder is set in the mounting machine body or the transport direction of the waste tape transport device is determined without considering the material of the waste tape.

[0012] The second waste tape recovery method of the present disclosure includes: A waste tape recovery method used in a component mounting line in which a plurality of component mounters are arranged side by side in a board transport direction, the method comprising: a mounter main body that receives a supply of components from a first tape feeder that supplies components using a tape made of a first material containing a plurality of components, or a second tape feeder that supplies components using a tape made of a second material, and mounts the components on a board; and a waste tape transport device that can transport the waste tape after supplying components both upstream and downstream in the board transport direction, the first tape feeder is set in the mounting machine bodies of a first group of consecutive component mounters, which includes a component mounter located furthest downstream in the board transport direction among the plurality of component mounters and a predetermined component mounter; the second tape feeder is set in a mounter body of at least one of the mounters adjacent to the predetermined mounter on the upstream side in the board conveying direction among a second mounter group other than the first mounter group; setting a waste tape transport direction in a waste tape transport device of the first component mounter group to the downstream side of the board transport direction; The gist of the present invention is that the waste tape transport direction in the waste tape transport device of the second component mounter group is set to the upstream side of the board transport direction.

[0013] In this second waste tape collection method, only waste tape made of the first material is transported downstream in the board transport direction, which makes it easier to separate the waste tape compared to when the tape feeder is set in the mounting machine body or the transport direction of the waste tape transport device is determined without considering the material of the waste tape.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of a component mounting line L. Fig. 2 is a perspective view showing the outline of the configuration of a component mounter 10. Fig. 3 is a front view of a waste tape transport device 60. Fig. 4 is an explanatory diagram showing the relationship of the waste tape transport device 60 on the component mounting line L. Fig. 5 is a block diagram showing the electrical connection relationship of a component mounting system 1.

[0016] The component mounting system 1 includes a component mounting line L, a management device 80 (see FIG. 5), and a collection box 90.

[0017] The component mounting line L includes a plurality of component mounters 10 (10A, 10B, 10C, 10D, 10E, 10F in this embodiment) arranged in the transport direction of the board S. As shown in FIG. 2, the component mounter 10 includes a mounter main body 11 that receives components from a tape feeder 20 that supplies components and mounts the components on the board S, a waste tape transport device 60, and a control device 70 (see FIG. 5).

[0018] The tape feeder 20 is a device that supplies components to the mounting machine main body 11. As shown in FIG. 2 , the tape feeder 20 is detachably set on the front portion of the main body frame 14 of the mounting machine main body 11. The main body frame 14 is provided on the base 12. The tape feeder 20 is equipped with a reel 23 around which tape is wound, and components are accommodated at predetermined intervals in each cavity of the carrier tape. These components are protected by a film covering the surface of the tape. When the tape is pulled out from the reel 23, the film is peeled off in the feeder section 24, exposing the components. Here, the carrier tape of such a tape feeder 20 may be made of paper or plastic, depending on the type and size of the components. In this embodiment, the tape feeder 20 using a paper carrier tape will be referred to as a first tape feeder 21, and the tape feeder 20 using a plastic carrier tape will be referred to as a second tape feeder 22.

[0019] The mounting machine main body 11 includes a board transport device 30, a component mounting device 40, and a tape cutting mechanism 25.

[0020] As shown in FIG. 2, the substrate transfer device 30 is configured as a dual-lane type transfer device provided with two substrate transfer paths, and is disposed on a support stand 18 provided in the middle section of the main body frame 14. The substrate transfer device 30 includes a conveyor belt device 33 and a backup device (not shown). The conveyor belt device 33 is provided on each substrate transfer path, and is driven to transfer the substrate S from left to right (substrate transfer direction) in FIGS. 1 and 2. The backup device backs up the transferred substrate S.

[0021] Component mounting device 40 is a device that mounts components on a board S that has been backed up by a backup device. Component mounting device 40 is housed within main body frame 14. As shown in FIG. 2, component mounting device 40 includes: a guide rail 42 provided along the Y-axis direction on the upper portion of main body frame 14; a Y-axis slider 44 that is movable along guide rail 42; a guide rail 46 provided along the X-axis direction on the underside of Y-axis slider 44; an X-axis slider 48 that is movable along guide rail 46; a head 50 attached to X-axis slider 48 and movable in the X and Y directions; and a suction nozzle 52 attached to head 50 so as to be movable in the Z-axis direction and rotatable about the Z-axis and capable of suctioning components. Furthermore, the component mounting device 40 also includes a mark camera 54 attached to the X-axis slider 48 for photographing the board positioning reference marks provided on the board S, a parts camera 56 attached to the support base 18 for photographing the components picked up by the suction nozzles 52, and a nozzle stocker 58 for stocking multiple types of suction nozzles 52 that can be attached to the head 50.

[0022] The tape cutting mechanism 25 is a mechanism for cutting the tape (waste tape) after components have been supplied and sending it downward. The tape cutting mechanism 25 includes a tape cutter 26, a tape duct 27, and a tape chute 28. The tape cutter 26 is for cutting the waste tape. The tape cutter 26 is provided between the tape duct 27 and the tape chute 28. The tape duct 27 and the tape chute 28 are for sending the waste tape downward. The tape duct 27 and the tape chute 28 are provided so as to be located behind the feeder section 24 when the tape feeder 20 is attached to the mounting machine main body 11. The waste tape that passes through the tape duct 27 is cut into small pieces by the tape cutter 26, falls through the tape chute 28, and is sent to the waste tape transport device 60.

[0023] The waste tape transport device 60 is a device that transports the waste tape sent from the tape cutting mechanism 25 to the outside of the component mounter 10 along the board transport direction. As shown in FIG. 3( a), the waste tape transport device 60 is configured as a belt conveyor device including a conveyor rail 62 that rotatably supports a drive wheel 61 a and a driven wheel 61 b, and a conveyor belt 64 that is stretched across the drive wheel 61 a and the driven wheel 61 b. In this waste tape transport device 60, a drive motor 66 is attached to the rotation shaft of the drive wheel 61 a. The drive motor 66 is a motor that can rotate in both forward and reverse directions. When the drive motor 66 is driven to rotate in the forward direction, the conveyor belt 64 is driven to transport the waste tape upstream (from right to left) in the board transport direction. On the other hand, when the drive motor 66 is driven to rotate in the reverse direction, the conveyor belt 64 is driven to transport the waste tape downstream (from right to left) in the board transport direction.

[0024] The conveyor rail 62 and the drive motor 66 are fixed to the base 12 via a support member 69 (see FIG. 2). Although not shown, the support member 69 is provided with an inclination angle adjustment mechanism that can adjust the inclination angle with respect to the base 12, so that the inclination angle for transporting the waste tape can be adjusted within a predetermined range (for example, within a range of +30 degrees to -30 degrees, with 0 degrees being horizontal) (see FIGS. 3(b) to 3(e)).

[0025] The conveyor rail 62 is configured so that its entire length can be expanded or contracted by a gas spring 68. When the gas spring 68 is contracted, it fits within the width of the base 12 in the X-axis direction (board transport direction), and when the gas spring 68 is extended, a portion of it protrudes from the base 12. Although not shown, the frame of the conveyor is provided with a locking mechanism for maintaining the gas spring 68 in the contracted state.

[0026] The conveyor belt 64 is adjusted in length so that it is in a relaxed state (see Figures 3(a) to (c)) when the conveyor rail 62 is contracted, and in a stretched state (see Figures 3(d) and (e)) with tension suitable for belt drive when the conveyor rail 62 is extended.

[0027] Here, consider a case where a component mounting line L is configured by installing multiple mounters 10A to 10F. As shown in FIG. 4, when multiple mounters 10 are installed side by side in the board transport direction, the waste tape transport devices 60 of each mounter 10 are aligned in a row in the board transport direction. The waste tape transport devices 60 (belt conveyor devices) of the component mounters 10A and 10B have their inclination angles adjusted to tilt upward to the left, and portions of them protrude from the base 12 in the waste tape transport direction, thereby overlapping vertically with the waste tape transport devices 60 (belt conveyor devices) of adjacent mounters 10. On the other hand, the waste tape transport devices 60 (belt conveyor devices) of the component mounters 10C to 10F have their inclination angles adjusted to tilt upward to the right, and portions of them protrude from the base 12 in the waste tape transport direction, thereby overlapping vertically with the waste tape transport devices 60 (belt conveyor devices) of adjacent mounters 10. This allows for smooth transfer of waste tape from one waste tape transport device 60 to an adjacent waste tape transport device 60, preventing the waste tape from falling during transfer. As a result, each waste tape transport device 60 can transport the waste tape to the end of the component mounting line L while transferring the waste tape to the waste tape transport device 60 of the adjacent component mounter 10. Furthermore, if the component mounters 10A, 10B consecutive from the most upstream on the component mounting line L are designated as a first component mounter group G1, and the remaining component mounters 10C to 10F are designated as a second component mounter group G2, the waste tape transport device 60 of the first component mounter group G1 can transport the waste tape upstream in the board transport direction, and the waste tape transport device 60 of the second component mounter group G2 can transport the waste tape downstream in the board transport direction.

[0028] The control device 70 is configured as a microprocessor centered on a CPU, and controls the entire component mounter 10. The control device 70 outputs control signals to the mounter main body 11, the tape feeder 20, and the waste tape transport device 60. The control device 70 is also connected to be able to communicate with the tape feeder 20, the control devices 70 of other component mounters 10, the management device 80, etc.

[0029] The management device 80 is a computer including a CPU 81, a ROM 82, a RAM 83, a storage 84, etc., and is connected to the control device 70 of the component mounter 10 so as to be able to communicate with it.

[0030] The collection box 90 is a box-shaped member that collects the waste tape that has been transported by the waste tape transport device 60 to the start or end of the component mounting line L.

[0031] Next, the component mounting process of the component mounting line L configured as described above will be described. In the component mounting process, first, the control device 70 controls the board transport device 30 until the board S is directly above the backup device. Next, once the board S is directly above the backup device, the control device 70 controls the backup device so that the board S is backed up. Next, the control device 70 controls the tape feeder 20 so that tape is fed from the reel 23 to supply components. The control device 70 then controls the X-axis slider 48 and the Y-axis slider 44 so that the suction nozzle 52 is directly above the supplied components. Next, the control device 70 lowers the suction nozzle 52 and applies negative pressure to the suction port of the suction nozzle 52, thereby suctioning the component onto the suction nozzle 52. After the component is thus sucked, the control device 70 raises the suction nozzle 52 and controls the sliders 44, 48 so that the component picked up by the suction nozzle 52 is directly above the mounting position for the board S. Then, the control device 70 lowers the suction nozzle 52 until the component is pressed against the mounting position on the board S, and applies positive pressure to the suction port of the suction nozzle 52, thereby releasing the suction of the component by the suction nozzle 52. By repeating this operation, each component is mounted on the board S. When all components that should be mounted by the control device itself have been mounted on the board S, the control device 70 controls the backup device to release the backup of the board S, and controls the board transport device 30 to transport the board S downstream.

[0032] Here, tape feeders 20 made of the same tape material can be set in each mounter main body 11 of the first component mounter group G1, and tape feeders 20 made of the same tape material can also be set in each mounter main body 11 of the second component mounter group G2. For example, as shown in Fig. 7, a first tape feeder 21 can be set in the first component mounter group G1, and a second tape feeder 22 can be set in the second component mounter group G2. In this case, in the waste tape transport device 60 of the first component mounter group G1, the rotation direction of the drive motor 66 is set to the forward direction so that the conveyor belt 64 transports the waste tape upstream in the board transport direction, and the rotation direction of the drive motor 66 is set to the reverse direction so that the conveyor belt 64 of the waste tape transport device 60 of the second component mounter group G2 transports the waste tape downstream in the board transport direction. In this way, the waste paper tape from the first tape feeder 21 and the waste plastic tape from the second tape feeder 22 are separated and collected in collection boxes 90 located on the sides of the starting and ending ends of the component mounting line L.

[0033] Furthermore, tape feeders 20 with different tape materials can be set in a mixed state in each mounter main body 11 of the first component mounter group G1, and tape feeders 20 with the same tape material can be set in each mounter main body 11 of the second component mounter group G2. For example, as shown in Fig. 8, first tape feeders 21 and second tape feeders 22 can be set in a mixed state in the mounter main body 11 of the first component mounter group G1, and the second tape feeder 22 can be set in the mounter main body 11 of the second component mounter group G2. In this case, in the waste tape transport device 60 of the first component mounter group G1, the rotation direction of the drive motor 66 is set in the forward direction so that the conveyor belt 64 transports the waste tape upstream in the board transport direction, and the rotation direction of the drive motor 66 is set in the reverse direction so that the conveyor belt 64 of the waste tape transport device 60 of the second component mounter group G2 transports the waste tape downstream in the board transport direction. In this way, paper waste tape and waste tape that is a mixture of paper and plastic waste tape are transported in opposite directions, making it easier to separate the waste tape compared to when the tape feeder 20 is set in the mounting machine main body 11 or the transport direction of the waste tape transport device 60 is determined without taking into account the material of the waste tape.

[0034] Next, a waste tape transport direction determination routine that determines the boundary between the first mounter group G1 and the second mounter group G2 and determines the waste tape transport direction of the first mounter group G1 and the second mounter group G2 when executing the component mounting process described above will be described with reference to FIGS. 6 to 9. FIG. 6 is a flowchart showing an example of the waste tape transport direction determination routine. FIGS. 7 to 9 are explanatory diagrams showing a state in which the tape feeders 20 are set in each mounter main body 11. This routine is stored in the storage 84 of the management device 80 and is executed by the CPU 81. Note that this process is performed on the component mounting line L before the component mounting process described above is executed.

[0035] When this routine starts, the CPU 81 first reads information about the tape feeders 20 used in the production of the substrates S from the storage 84, and classifies the tape feeders 20 into first tape feeders 21 and second tape feeders 22 for each tape material (S100). This information about the tape feeders 20 includes information about the material that makes up the tape in the tape feeders 20, and information about restrictions on the placement position of the tape feeders 20.

[0036] Next, the CPU 81 determines whether there is a tape feeder 20 with a placement position restriction (S110). A tape feeder 20 with a placement position restriction (hereinafter, a tape feeder 20 with a placement position restriction) is a second tape feeder 22 that supplies components to be mounted on the board S before components supplied from the first tape feeder 21, or a first tape feeder 21 that supplies components to be mounted on the board S before components supplied from the second tape feeder 22. Examples of tape feeders 20 with a placement position restriction include a tape feeder 20 that supplies components that are shorter than other adjacent components among components used in the production of the board S, a tape feeder 20 that supplies components to be mounted on the board S before shielding components, and a tape feeder 20 that supplies shielding components. A shielding component is a component that is mounted on the board S so as to cover other components mounted on the board S from above. In this embodiment, the tape feeders 20 with placement position restrictions are the second tape feeder 22 that must be set in the mounter body 11 of the component mounter 10A and the first tape feeder 21 that supplies components that will be mounted on the board S after the components supplied from the second tape feeder 22. Therefore, the CPU 81 determines whether or not there is a second tape feeder 22 that must be set in the mounter body 11 of the component mounter 10A.

[0037] If a negative determination is made in S110, the CPU 81 determines the first mounter group G1 and the second mounter group G2 according to the ratio of the first tape feeders 21 (S120). This process is executed as follows. That is, the CPU 81 acquires the number of first tape feeders 21 and the number of second tape feeders 22. Next, the CPU 81 derives the ratio of the first tape feeders 21. The ratio of the first tape feeders 21 is the ratio of the first tape feeders 21 to all the tape feeders 20. Next, the CPU 81 derives the number of mounters 10 belonging to the first mounter group G1 (the number of mounters 10 that belong to the first mounter group G1 and will be lined up consecutively when the first mounter group G1 is determined). Specifically, the CPU 81 derives an integrated value by multiplying the number of mounters 10 that make up the component mounting line L by the ratio of the first tape feeders 21. If the integrated value is an integer, the CPU 81 sets the integrated value as the component number. On the other hand, if the integrated value is a decimal, the CPU 81 executes the following rounding process. If there are more first tape feeders 21 than second tape feeders 22, the CPU 81 rounds up the integrated value and sets the resulting value as the component number. If there are fewer first tape feeders 21 than second tape feeders 22, the CPU 81 rounds down the integrated value and sets the resulting value as the component number. The CPU 81 then determines the component mounters 10 that are lined up consecutively by the component number starting from the component mounter 10A located at the most upstream position as a first component mounter group G1, and determines the component mounters 10 other than the first component mounter group G1 as a second component mounter group G2.

[0038] Next, the CPU 81 determines to set the first tape feeder 21 in the first component mounter group G1 and to set the second tape feeder 22 in the second component mounter group G2 (S130).

[0039] Here, an example of a state in which the first mounter group G1 and the second mounter group G2 have been determined according to S120 and S130, and the first tape feeders 21 and the second tape feeders 22 have been set in the mounter main body 11 will be described with reference to FIG. 7. In FIG. 7, the ratio of the numbers of the first tape feeders 21 to the second tape feeders 22 is 2:3. In this case, the ratio of the first tape feeders 21 is 0.4. Also, in FIG. 7, since the component mounting line L has six mounters 10, the integrated value is 2.4. Then, 2, obtained by rounding down 2.4, becomes the constituent number. Therefore, the two consecutive mounters 10 (mounters 10A and 10B) including the mounter 10A, become the first mounter group G1, and the other mounters 10 (mounters 10C to 10F) become the second mounter group G2.

[0040] On the other hand, if an affirmative determination is made in S110, the CPU 81 determines to set a tape feeder 20 with placement position restrictions in the mounter main body 11 of the component mounter 10A (S140).

[0041] Next, the CPU 81 determines the first component mounter group G1 and the second component mounter group G2 according to the adjusted ratio obtained by adjusting the ratio between the first tape feeders 21 and the second tape feeders 22 (S150). The ratio is adjusted by adding the number of first tape feeders 21 and subtracting the number of second tape feeders 22 by that number when the second tape feeders 22 are arranged upstream of the first tape feeders 21 in the board conveyance direction due to arrangement position restrictions, and recalculating the ratio. In S150, the CPU 81 performs the same process as in S120 except that the adjusted ratio is used instead of the ratio of the first tape feeders 21.

[0042] Then, the CPU 81 decides to set the first tape feeder 21 to the component mounters 10 belonging to the first component mounter group G1 except for the component mounter 10A, and to set the second tape feeder 22 to the second component mounter group G2 (S160).

[0043] An example of a state in which the first mounter group G1 and the second mounter group G2 are determined according to S140 to S160, and the first tape feeders 21 and the second tape feeders 22 are set in the mounter main body 11 will be described with reference to FIG. 8. In FIG. 8, because some of the second tape feeders 22 are arranged upstream of the first tape feeders 21 in the board conveyance direction due to limitations on placement positions, the ratio between the number of first tape feeders 21 and the number of second tape feeders 22 is adjusted, and the adjusted ratio is 0.5. Also, in FIG. 8, because the component mounting line L has six mounters 10, the integrated value is 3. And because rounding processing is not required, the constituent number is 3. Therefore, the three mounters 10 (10A to 10C) lined up in succession, including the mounter 10A, form the first mounter group G1, and the other mounters 10 (10D to 10F) form the second mounter group G2.

[0044] 8, the first component mounter group G1 includes a mixture of mounter main bodies 11 (mounter main bodies 11 of component mounters 10B and 10C) in which the first tape feeder 21 is set and a mounter main body 11 (mounter main body 11 of component mounter 10A) in which the second tape feeder 22 is set. However, as shown in FIG. 9, the first component mounter group G1 may include a mixture of the first tape feeder 21 and the second tape feeder 22 set in one mounter main body 11 (mounter main body 11 of component mounter 10A).

[0045] After S130 or S160, the CPU 81 determines the waste tape transport direction in the first component mounter group G1 to be upstream of the board transport direction (white arrow pointing left in Figures 7 to 9) (S170), and determines the waste tape transport direction in the second component mounter group G2 to be downstream of the board transport direction (white arrow pointing right in Figures 7 to 9) (S180).

[0046] Next, the CPU 81 instructs the worker to set the tape feeders 20 (S190). Specifically, the CPU 81 causes a display device (not shown) provided in the management device 80 to display information about the tape feeders 20 required for the production of the substrate S and information about the set positions at which the tape feeders 20 should be set. After checking this information, the worker prepares the tape feeders 20 required for the production of the substrate S and sets the tape feeders 20 at the instructed set positions. Note that the setting of the tape feeders 20 may be performed automatically by an automatic exchange device (not shown).

[0047] Then, the CPU 81 instructs the control device 70 of each mounter 10 as to the waste tape transport direction (S200). When the instruction for the waste tape transport direction is input, the control device 70 of each mounter 10 sets the rotation direction of the drive motor 66 so that the waste tape transport direction becomes the instructed direction, and controls the tilt angle adjustment mechanism to adjust the tilt direction and tilt angle of the waste tape transport device 60. After S200, the CPU 81 ends this routine.

[0048] Here, the correspondence between the main elements of the embodiment and the main elements of the present disclosure will be described. That is, component mounting line L corresponds to the component mounting line, first tape feeder 21 corresponds to the first tape feeder, second tape feeder 22 corresponds to the second tape feeder, mounter main body 11 corresponds to the mounter main body, component mounters 10A to 10F correspond to multiple component mounters, first component mounter group G1 corresponds to the first component mounter group, and second component mounter group G2 corresponds to the second component mounter group.

[0049] In the component mounting line L described above, only paper waste tape is transported upstream in the board transport direction. Therefore, it is easier to separate the waste tape compared to when the tape feeder 20 is set in the mounting machine main body 11 or the transport direction of the waste tape transport device 60 is determined without considering the material of the waste tape.

[0050] Furthermore, in the component mounting line L, a second tape feeder 22 may be set in the mounting machine main body 11 of the second component mounter group G2. In this way, waste paper tape and waste plastic tape can be separated.

[0051] It goes without saying that the present disclosure is not limited to the above-described embodiments, and can be embodied in various forms as long as they fall within the technical scope of the present disclosure.

[0052] In the embodiment described above, the first tape feeder 21 is set in the mounter main body 11 of the first component mounter group G1, and the second tape feeder 22 is set in the mounter main body 11 of the second component mounter group G2. However, as shown in FIGS. 10 and 11 , the first tape feeder 21 may be set in the mounter main body 11 of the first component mounter group G1, and the first tape feeder 21 and the second tape feeder 22 may be set in the mounter main body 11 of the second component mounter group G2. That is, as shown in FIG. 10 , in the second component mounter group G2, the mounter main body 11 in which the first tape feeder 21 is set (the mounter main body 11 of the component mounter 10F) and the mounter main body 11 in which the second tape feeder 22 is set (the mounter main body 11 of the component mounters 10C to 10E) may be arranged in a mixed manner. 11, in the second component mounter group G2, the first tape feeder 21 and the second tape feeder 22 may be set in a single mounter main body 11 so as to be mixed together.

[0053] In the above-described embodiment, the component mounters 10A located at the most upstream position in the board transport direction to the consecutively lined-up component mounters 10B are defined as the first component mounter group G1. However, as shown in Fig. 12, the component mounters 10 (10F, 10E, 10D) located at the most downstream position in the board transport direction to the consecutively lined-up component mounters 10 may be defined as the first component mounter group G1, and the other component mounters 10 (component mounters 10A to 10C) may be defined as the second component mounter group G2. In this case, as shown in Figs. 13 and 14, the mounter main body 11 of the first component mounter group G1 may be set with a mixture of the first tape feeder 21 and the second tape feeder 22, and the mounter main body 11 of the second component mounter group G2 may be set with only the second tape feeder 22. 13, in the first component mounter group G1, the mounter main body 11 (the mounter main body 11 of the component mounters 10D and 10E) in which the first tape feeder 21 is set and the mounter main body 11 (the mounter main body 11 of the component mounter 10F) in which the second tape feeder 22 is set may be arranged so as to be mixed. Alternatively, as shown in FIG. 14, in the first component mounter group G1, the first tape feeder 21 and the second tape feeder 22 may be set so as to be mixed in one mounter main body 11 (the mounter main body 11 of the component mounter 10F). Also, as shown in FIGS. 15 and 16, the first tape feeder 21 may be set in the mounter main body 11 of the first component mounter group G1, and the first tape feeder 21 and the second tape feeder 22 may be set so as to be mixed in the mounter main body 11 of the second component mounter group G2. 15, in the second mounter group G2, the mounter main body 11 (the mounter main body 11 of the mounter 10A) on which the first tape feeder 21 is set and the mounter main body 11 (the mounter main body 11 of the mounter 10B, 10C) on which the second tape feeder 22 is set may be arranged so as to coexist. Alternatively, as shown in FIG. 16, in the second mounter group G2, the first tape feeder 21 and the second tape feeder 22 may be set so as to coexist in one mounter main body 11 (the mounter main body 11 of the mounter 10A).

[0054] In the above-described embodiment, the management device 80 determines the first component mounter group G1 and the second component mounter group G2, and determines the waste tape transport direction of the waste tape transport device 60. However, an operator on the component mounting line L may determine the first component mounter group G1 and the second component mounter group G2, and determine the waste tape transport direction of the waste tape transport device 60.

[0055] In the above-described embodiment, the present disclosure has been described as a component mounting line L, but it may also be a method for collecting waste tape, a management device 80, or a component mounting system 1. [Industrial Applicability]
